The line graph predicts the proportion of the population aged 65 and above in three different continents from the year 1940 to 2040.
Overall, Japan will have the highest number of elderly people aged 65 and above. Sweden and the USA will have fewer senior citizens compared to Japan from 1940 to 2040.
In 1940, the highest number of elderly individuals was in the USA, accounting for 9%. Sweden had the second-highest senior citizen population at around 7% in 1940. In Japan, the lowest proportion of elderly residents was approximately 5%. Over the next two decades, the percentage of older people in the USA and Sweden increased to 10% and 9% respectively. In contrast, Japan’s elderly population dropped to 2% by 1960.
By 1980, the elderly population in Japan remained stable, while the USA and Sweden experienced a steady increase in the older population, reaching around 15% and 12% respectively.
After four decades, Japan witnessed a significant increase in the proportion of elderly residents to 10%, while the USA’s elderly population gradually declined to 9%. Sweden showed fluctuations in the elderly population, reaching 20%. In 2040, the projected elderly population is expected to rise to approximately 23% in the USA, 25% in Sweden, and almost 26% in Japan, making it the highest among the three countries over the course of 100 years.
